IMPROVEMENT IN ENDLESS WlREWAVS.

Specification forming part of Letters Patent No. 162,915, dated May 4,1875; application filed March 8, 1875.

CASE A.

To all whom it may concern:

Be it known that I, ANDREW S. HALLIDIE, of San Francisco city andcounty, State of California, have invented Improvements in EndlessWVire-Rope WVays; and I do hereby declare the following description andaccom panyin g drawings are sufficient to enable any person skilled inthe art or science to which it most nearly appertains to make and use mysaid invention or improvel'nent, without further invention orexperiment.

My invention relates to an improved guard or keeper for preventing wireropes and other ropes which are supported on pulleys from leaving thepulley-groove in which they bear.

Where a great length of rope, such as is necessary in the constructionof wire-rope ways, and in the propulsion of vehicles along a track, issupported at intervals on pulleys, some guard or fender is required toprevent the rope from jum pin gout of the pulley-groove.

Heretofore two pulleys have been used for this purpose, one of whichserved to support the rope, while the other was placed directly aboveit, so that the grooves of the pulleys would be opposite each other.

My invention relates to a substitute for th s upper pulley, which isfully described in the following specification, in which reference ishad to the accompanying drawings, in which- Figure l is a perspectiveview of my invention.

Let A represent the horizontal beam which supports the rope-supportingpulley B. The journal upon which the pulley B rotatesis secured to theunder side of the beam A, and

projects out far enough beyond the end of the beam to permit the pulleyto rotate in a vertical plane at right angles to the end of the beam, asshown. To the upper side ot the beam A I secure a block, C, which is soconstructed that it will overhang the upper edge of the pulley, asshown. That portion of the block C which is next to the inside face ofthe pulley extends down far enough below the edge of the pulley toprevent the rope from jumping out of the groove to the inside of thepulley, while the portion which extends above and projects across thegroove or edge of the pulley, will keep the rope down to its place. Thespace f, between the outside end of the block C and edge of the pulley,will serve to admit the rope to the groove, and permit the passage ofthe saddle-shank, and, being just space enough to admit the rope intothe groove there will be no danger of the rope getting to the outside ofthe pulley.

I thus provide a guard or keeper which will be cheap and equally aseffective as the doublepulley arrangement heretofore used.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In combination with the rope-snpportin g pulley B, the fixed block C,arranged to overhang the upper edge of the pulley and extend down belowits inside edge, so as to serve as a guard or keeper for the rope,substantially as above specified.
